EDGE-BLACKIN MACHINE.

Specification of Letters Patent. Application filed June 7, 1905.

Serial N0.Lj264,040.

To all whom it may concern:

lle it known that I, lViLLL-iM E. VVENTZEL, a citizen of the United States, residing at Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in ildge-Blacking Machines, of which the following description, in connection with the cconipanying drawing, is a specification,

like letters on the drawings representing like parts.

This invention has for its object the production of a simple and eflicient machine for applying blacking or other coloring solution to the edge of the sole and heel of a boot shoe.

After a boot or shoe has been completed is necessary to coat the exposed edge of the sole and heel, not only upon the periphery, but also upon the top of that portion extending slightly out beyond the vamp. The coating solution must be applied evenly, and without being daubed over the vamp or other portion of the shoe where it would produce an unsightly appearance. In this operation, as in all operations connected with the manufacture of boots and shoes, it is desirable to obtain as rapid and efiicient work as possible. In the machine of the present invention the shoe is held up against a rotating brush, the coating material is fed onto the brush in just'th-e desired amount, and the brush is guided along the edge of the sole and heel, the vamp is protected from contact with the brush, and any superfluous from the brush and guide.

The drawings show a machine embodying in its preferred form the invention, although it is obvious that many changes in construction, arrangement and operation of the parts may be made without departing from the spirit of the invention.

In the drawings, Figure 1 represents a rear elevation, partially in cross-section, of the machine; 2 a plan view of the reser voir and the mechanism mounted on the top thereof; Fig. 3 an enlarged cross-section through the upper portion of the reservoir and the mechanism mounted thereon, taken through the axis thereof and on the line ;ra2, of Fig. 2; Fig. t is an enlarged crosssection of the lower end of the reservoir and the valve, the said section being taken at right-angles to that appearing in Fig. 1'

he solutions usually employed for the coating of the sole edge settle rapidly, and become in the lower portion of the tank or reservoir containing them thick theref It is necessary,

and

pasty. ore, to stir the solution frequently to keep it of the required consistency. To secure this end a stirrer D is mounted in the tank, and is shown as comprising two wide bla only stir the solution des D, D, which not but scrape the sides of the tank reached by the solution, and a stirring and scraping blade D IOI'IH, stirring the sol the tank face of the tanl voir, and carries at its keyed thereto at D of triangular ution at the bottom of and scraping also the bottom sur- The stirrer fast on a hollow shaft D journaled in suitable bearing extensions D is mounted D D of the reserupper end a pulley D, adapted to rotate the shaft and to slide lengthwise thereof, for a purpose to be describ The pulley D is during the operation continuously rotated of the machine from the main shaft C, by means of a belt E, running over idlers E fast to said shaft.

, and around a. pulley E The lower end of the reservoir carries a valve to feed the brush in the desired sary that this valve solution out upon the quantity. It is necesshould be capable of regulation to supply the eXact amount needed, according to the size of the surface to be coated, the speed with which the work is done, and the consiste ployed. WVhenever th ing idle, and even when the stirrer is run ncy of the solution eme machine is left stand- OF LYNN, MASSACHU- ning and the machine is not being used, the solution will settle and thicken around the valve, and will start toflow with difficulty, or spurt out suddenly. The obviation of this diiiiculty is one of the most important features of the present invention. Herein means are provided for stirring up or agitating the solution at the outlet through the valve, so that through the valve when the valve is open. This is secured by rotating the valve when it is lifted from its seat, and also by rotating the end of the stirrer I), having its bearing in the outlet of the reservoir and forming itself an outlet for the solution. The tubular end of the stirrer which projects int-o the reservoir outlet forms in fact an inner mov able wall of the outlet, for the liquid is fed through the tubular end portion of the stirrer. The rotation of the stirrer therefore agitates the liquid at the outlet by moving the wall of the ope-ning. through which the liquid is fed. In the construction shown and described both these parts-are rotated and rotated in the same direction, but the advantages of the invention w-"ll be secured to a large extent by rotating either part alone, the other remaining stationary, or by rotating both parts in opposite directions, but the construction shown has been found to work with great success and to be a simple constructi'on.

A nozzle F is screwed. or otherwise'fastened onto the lower projecting end of the reservoir, and carries a preferably conical valveseat F. A valve F shaped to fit the seat is mounted on the end of a long rod F extending up through the hollow shaft D At its upper end the rod F has fastened thereon a clutch or friction disk F and the rod is journaled in a frame Gr, on topof the reservoir and has a thrust-bearing against the frame. This construction is obtained by forming the friction disk F with an integral tube F embracing the rod W, the whole being keyed to the rod as at I A cap F screwed onto the end of the rod, and abutting against the sleeve F holds the parts together. The thrust-bearing is preferably formed by a disk H, surrounding the tube, and separated from the frame G by a spiral spring H, and a ball-bearing H is located between the disk II and the disk F.

The pulley D is provided with a friction surface D cooperating with the friction disk F and when the valve is closed these parts are slightly separated, as indicated in Fig. 3.

The valve is lifted from its seat by giving a vertical movement to the pulley D bringing it into contact with the friction disk F This is secured by mounting integrally of the bearing D cooperating cams. Cams M, M, are mounted diametrically op posite fast to the top of the tank, and cam surfaces M, cooperating with the cams M,

the liquid will flow readily i and the sleeve M A lever is clamped at M around and to the sleeve M \Vhen, now, the lever is pulled it will rotate the sleeve M and cause the cam surfaces M to ride up on the cams M, thus raising the sleeve M and with it the pulley I). The lever h F is operated by a chain N run. ning over a suitable pulley N, and connected with a suitable treadle or the movement of which treadle is limited by a stop N In operation the belt shipper C is moved to bring the belt onto the fast pulley and at once the stirrer is set in operation and stirs the solution continually. The shoes are then presented to the brush G, and at the same time the desired amount of solution is allow-ed to run out on the brush. This is done by depressing the treadle N which swings the lever M and through the cams raises the pulley D into contact with the friction disk F This again lifts the valve F from its seat, but at the same time causes the valve to rotate, because the means (the pulley etc.) for lifting the valve from its seat is itself in constant rotation. Immediately, therefore, the valve is lifted from its seat it turns or stirs up the thickened or coa-gulated solution and allows it to run out freely onto the brush. \Vhen the necessary amount hasbeen supplied the lever is released and a spring 0 returns the parts to their normal position and the valve drops backonto its seat.

The extent to which the valve F is lifted from its seat is controlled in various ways. First, the movement of the treadle is limited by the stop N second, the movement of the lever N may be adjusted by a turn-buckle N, or similar device,located in the chain N, and third, the cam sleeve M may be adjusted, rotarily within the lam-ping lever, M

The solution is supplied to the tank through a cover opening P, the bottom of which is a sieve I.

In the construction shown the tubular shaft D has its bearing in the lower end 0 the reservoir, and to allow the feed of the solution to the valve openings D are formed in the sleeve, and sufficient space is provided between the rod F and the inner wall of the tube to allow of the flow of the solution.

In coating the sole and heel edge, the brush must not only coat the periphery of the sole and heel but must reach into the recess formed between the vamp and the sole, to coat thoroughly the exposed top of the sole or heel. The brush is therefore con structed of two sections, the exterior of comparatively long and stiffbristles It, and the interior of comparatively short and pliable bristles R. The former reach over and coat the upper exposed edges, the latter apply the coating to the periphery. The width'of. the sections may be varied according to the M, are formed on other devlce N", p

333,009 8" width of the work to be coated. In order to protect the coating solution from being applied to the vamp or anything but the sole, a metallic disk R of slightly less diameter than the bristles is mounted 011 the exterior of the brush. This disk serves not only to guard the parts of the shoe, but also serves as a guide for presenting the heel and sole to the brush. This disk is allowed to run in the recess between the edge of the sole or heel and the vamp. In this manner the shoe can be readily and accurately presented to the brush.

In order to prevent any slight surplus of the solution from running onto the surface of the disk It or dropping off from the brush onto the shaft C wipers are provided. The wipers consist of two plates S, S, adjustable with respect to each other so as to press lightly against the opposite sides of the brush and guard, and mounted by an arm S to the frame of the machine. These plates are covered with a suitable absorbent material S preferably in the form of a sleeve slipped on over the plates so as to be capable of removal when desired. These absorbent plates remove any of the solution running over onto the guard R or liable to drip onto the shaft C and keep the whole clean and neat. In practice when the machine is properly handled they are found to take up very little of the solution and will need comparatively infrequent replacing.
